-------------------------------------
Summary: FileNotFoundException when using storm with apache tika
Key: STORM-402
URL: https://issues.apache.org/jira/browse/STORM-402
Project: Apache Storm (Incubating)
Issue Type: Bug
Affects Versions: 0.9.2-incubating, 0.9.3-incubating
Environment: Ubuntu 14.04, amd64
Reporter: Milad Fatenejad
Priority: Minor
I have started using storm with apache tika for text extraction and I
encountered a FileNotFoundException emanating from the download-storm-code
method in supervisor.clj when running in local mode (I am able to submit to a
remote cluster that I created):
7887 [Thread-5] INFO backtype.storm.daemon.supervisor - Downloading code for

In this case, the download-storm-code method in supervisor.clj is trying to
load resources from the URL:
jar:file:/home/milad/.m2/repository/edu/ucar/netcdf/4.2-min/netcdf-4.2-min.jar!/resources
The relevant code in download-storm-code seems to be:
(log-message "Copying resources at " (str url) " to " target-dir)
(FileUtils/copyDirectory (File. (.getFile url)) (File. target-dir))
Since the url is of the form:
jar:file:/home/milad/.m2/repository/edu/ucar/netcdf/4.2-min/netcdf-4.2-min.jar!/resources
the getFile method simply returns:
file:/home/milad/.m2/repository/edu/ucar/netcdf/4.2-min/netcdf-4.2-min.jar!/resources
which is incorrect and leads to the exception.
